Turn based combat is quite hard to make engaging.
In a way. All the suggestions you make is surface presentation stuff - something that can make mechanically dull action game work, but I doubt it will help turn based game much.
TB spotlights mechanics and decision-making, and key to making TB work is nailing the gameplay. Larian presents players with a rich amount of choice but it fails hard in offering players interesting choices - combat is too unbalanced, classes made too homogenous. DnD isn't a top shelf gameplay experience to begin with, and BG3 is much worse then that thanks to Larians changes.
Real-time nature and lack of feedback in BG1&2 made shallow underlying mechanics easier to glance over. BG3 doesn't have that luxury.
